JOHN GOLDSBOROUGH, OF PHILADELPHIA, PENNSYLVANIA.

IMPROVEMENT IN HAND-STAMPS.

Specification forming part of Letters Patent No. 150,858, dated May 12, 1874 application filed March'2, 1874.

To all whom it may concern:

Be it known that I, JOHN GOLDSBOROUGH, of Philadelphia, Pennsylvania, have invented an Improvement in Hand-Stamps, of which the following is a specification:

The object of my invention is to securely connect a detachable die-plate to the base or plunger of a hand-stamp by adapting the opposite bent edges to a of the said die-plate to the correspondinglybeveled edges b b of the projection d on the base B of the stamp, as shown in the vertical section Figure 1, of the accompanying drawing, or to beveled edges on the plunger D, as shown in the elevation, Fig. 2, the said beveled edges b serving in both cases as guides upon which the overlapping die-plate A can be caused to slide in connecting or disconnecting it.

In Fig. l the saturated ribbon f which passes over the die It secured to the dieplate A is wound upon rollers i c contained within the base of the instrument; and in Fig. 2 all of these parts are secured to and move with the plunger.

My invention, which is applicable to both well-known styles of instruments has the following advantages: The method of attaching the die-plate is secure and simple. There are no projections to interfere with the adjustment of the saturated ribbon, which slides freely over the rounded edges (0 a of the die-plate, and the latter occupies the entire width of the portion of the base or plunger, to which it is attached, but without extending beyond the same, so that the die h, whether wide or narrow, must be solidly backed throughout, and the impressions obtained will consequently be uniform and perfect. When detachable type for dating, &c., are used in connection with the die, as shown in the perspective view, Fig. 3, I use a plate, F, for holding the said type in place when the dieplate is disconnected with the detachable die-plate A and its recessed die h, all substantially as and for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN GOLDSBORO UGI-I.
